    Climatologists find familiar fluctuations in Pacific's past - test. “During past ice ages the tropical Pacific Ocean behaved rather as it does today in an El Niño event, bringing downpours to some places and drought to others.” Thus began a 2002 article Nature magazine (12 Jul 2002) For example, it could explain the low atmospheric levels of greenhouse gases, such as carbon dioxide, methane and nitrous oxide, during the last ice age. It is not clear whether this was a cause or a consequence of the difference in global climate, but such decreases would have lowered global temperatures still further,...

    Virginia Gov. Ralph Northam is poised to implement a new regulation without legislative approval to join 10 other states in a climate change agreement based on restricting carbon dioxide emissions from coal-fired power plants.But lawmakers, policy analysts, and tea party activists in Virginia who oppose what they consider costly regulations of industry are raising questions about the economic and scientific arguments underpinning the proposed rule.They say the Virginia General Assembly should have a straight up-or-down vote on Northam’s plan, in part to ensure that any revenue the governor raises from “carbon trading” is collected and dispersed in a manner consistent...

    For a potential prize of $1 million, the government space agency is inviting the public to submit ideas about how to turn carbon dioxide, which is plentiful on the red planet, into glucose, which is more useful for human consumption. The goal is to allow astronauts to visit Mars with fewer materials and ultimately “to enable humans to live and thrive on the planet.” ... NASA has also asked for help controlling a humanoid robot in a simulated mission to Mars and with building “sustainable housing for deep space.” NASA isn’t the only organization trying to get people on Mars....

    Take a wild guess what country is reducing its greenhouse gas emissions the most? Canada? Britain? France? India? Germany? Japan? No, no, no, no, no and no. The answer to that question is the U.S. of A. Wow! How can that be? This must be a misprint. Fake news. America never ratified the Kyoto Treaty some two decades ago. We never enacted a carbon tax. We don't have a cap-and-trade carbon emission program. That environmental villain Donald Trump pulled America out of the Paris climate accord that was signed by almost the entire rest of the civilized world. Yet the...

    Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO2 from the atmosphere for long-term storage, thus countering the global warming effect of atmospheric CO2. This work is presented at the Goldschmidt conference in Boston. Project leader, Professor Ian Power (Trent University, Ontario, Canada) said: "Our work shows two things. Firstly, we have explained how and how fast magnesite forms naturally. This is a process which takes hundreds to thousands of years in nature at Earth's surface. The second...
  • Carbon Dioxide ‘Leak’ in Southern Ocean May Have Warmed Earth for 11,000 Years

    “We think we may have found the answer. Increased circulation in the Southern Ocean allowed carbon dioxide to leak into the atmosphere, working to warm the planet,” said Princeton University’s Professor Daniel Sigman, co-author of the study. For years, researchers have known that growth and sinking of phytoplankton pumps carbon dioxide deep into the ocean, a process often referred to as the ‘biological pump.’ “The biological pump is driven mostly by the low latitude ocean but is undone closer to the poles, where carbon dioxide is vented back to the atmosphere by the rapid exposure of deep waters to the...

    James Hansen issued dire warnings in the summer of 1988. Today earth is only modestly warmer. James E. Hansen wiped sweat from his brow. Outside it was a record-high 98 degrees on June 23, 1988, as the NASA scientist testified before the Senate Committee on Energy and Natural Resources during a prolonged heat wave, which he decided to cast as a climate event of cosmic significance. He expressed to the senators his “high degree of confidence” in “a cause-and-effect relationship between the greenhouse effect and observed warming.” With that testimony and an accompanying paper in the Journal of Geophysical Research,...

    In a NASA town hall yesterday (May 17), NASA's new administrator, Jim Bridenstine, said that he knows Earth's climate is changing, and that humans contribute to it "in a major way," also supporting NASA's research into that important area. The statement is significant because Bridenstine has expressed doubt about human-caused climate change in the past, causing some to question his suitability to lead a fact-focused NASA. In 2013, as an Oklahoma congressman, Bridenstine claimed there was no current trend toward global warming. More recently, such as in his NASA administrator confirmation hearings last November, he has acknowledged that human activity...

    The demonization of the “miracle molecule,” carbon dioxide, continued last week with the announcement that its concentration had reached 410 parts per million (ppm). Nearly all reporting of this noted that this was the highest level in 800,000 years and predicted a host of associated climate calamities. While the current concentration of this vital gas is about 40% higher than at the start of the Industrial Revolution, unreported is that Earth has been suffering from steadily decreasing and perilously low concentrations of CO2. Until the consumption of fossil fuels began liberating this important gas from ancient rocks , the Earth...

    Concrete is one of the most widely used building materials in the world, but it also is responsible for about 5% of all global carbon dioxide emissions according to the Earth Institute at Columbia University. Those emissions result directly from the conversion of limestone into cement and indirectly by burning fuel to heat the limestone to 1400º C, the temperature required to initiate the conversion process. “Cement manufacturing is highly energy and emissions intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of...

    Enzymatic liquid membrane design and mechanism of carbon dioxide capture and separation. The Sandia/University of New Mexico membrane is fabricated by formation of 8-nanometer diameter mesopores. Using atomic layer deposition and oxygen plasma processing, the silica mesopores are engineered to be hydrophobic except for an 18-nm-deep region at the pore surface which is hydrophilic. Through capillary condensation, carbonic anhydrase enzymes and water spontaneously fill the hydrophilic mesopores to form an array of stabilized enzymes with an effective concentration greater than 10 times of that achievable in solution. These catalyze the capture and dissolution of carbon dioxide at the upstream surface...

    In a bizarre irony, the German daily newspaper Die Welt has proclaimed U.S. President Donald Trump “the most successful climate protector in the world” after a new global climate report revealed that U.S. carbon dioxide emissions dropped dramatically during Trump’s first year in office.... The United States led the small pack of countries that managed to lower greenhouse gas emissions, accompanied by UK, Japan, and Mexico. According to IEA figures, the United States managed to reduce CO2 emissions in 2017 by 0.5 percent, or 25 million tons, to 4810 million tons. ... Mr. Wetzel doffed his hat to President Trump,...

    Billions of years ago... our planet’s primordial atmosphere was toxic to life as we know it, consisting of carbon dioxide, nitrogen and other gases. However, by the Paleoproterozoic Era (2.5–1.6 billion years ago), a dramatic change occurred where oxygen began to be introduced to the atmosphere – known as the Great Oxidation Event (GOE). [S]cientists were not sure if this event – which was the result of photosynthetic bacteria altering the atmosphere – occurred rapidly or not. ... Based on newly-discovered geological evidence, the team concluded that the introduction of oxygen to our atmosphere was “more like a fire hose”...

    Fertilisers washing into lakes could increase methane emissions, potentially undoing progress in addressing climate change. The biggest human influence on climate change and global warming is the release of greenhouse gases into the atmosphere. Now research published in the journal Limnology and Oceanography Letters is the first to show how the size of lakes and the nutrients in their waters from fertilisers are contributing to that influence. "Our research pioneers a new way of determining the global atmospheric effect of lakes using satellite information on lake greenness and size distribution," said Professor John Downing. "Our research team assembled the largest...

    Earth’s surface will almost certainly not warm up four or five degrees Celsius by 2100, according to a study released Wednesday which, if correct, voids worst-case UN climate change predictions. A revised calculation of how greenhouse gases drive up the planet’s temperature reduces the range of possible end-of-century outcomes by more than half, researchers said in the report, published in the journal Nature. “Our study all but rules out very low and very high climate sensitivities,” said lead author Peter Cox, a professor at the University of Exeter.
